Glenara Bates, 2, was brought to the hospital by her mother Andrea Bradley on March 29.

Police said when the toddler was brought to the hospital, she was already dead.

The Hamilton County Coroner's Office said the girl died due to trauma and starvation.

Hamilton County Prosecutor Joe Deters said the girl was starved, beaten with a belt, bitten and dropped on her head. She had more than 100 wounds, including broken teeth, he said.
